In April 1938, a man calling himself Josef Hofmann arrives at a boarding house in Hamm, Germany, and lets a room from the widow who owns it. Fifty years later, Walter Gersdorff, the widow's son, who was 11 years old in the spring of 1938, discovers the carefully hidden diary the boarder had kept during his stay, even though he should never have written any of its contents down. What Walter finds is a scathing chronicle of one the most tumultuous years in German history, narrated by a secret agent on a deadly mission.

A Russian defector is found brutally murdered in a London hotel. Only four people knew he had turned - the four most important and powerful figures in Whitehall. There's only one conclusion - a mole has infiltrated the highest levels of the nation's security. Operating in secret from within Westminster's darkest corners, former spy Solomon Vine must uncover the traitor. Because Britain's future hangs in the balance. And with it the fate of the whole world.
